Example Questions

A mainframe customer would like to receive a proposal for a mainframe storage system with 120 TB raw capacity. The mainframe server load is not too high, and they need drives with the lowest possible power consumption to keep operating costs low. The customer will not increase the capacity of their mainframe applications in the future but rather invest later into their Power servers. Which of the following solutions best meets these requirements at the lowest cost? The value-based licensing for the Operating Environment License (OEL) is priced based on what characteristics? A customer has a DS8000 with 100 TB raw capacity’ installed and running in their data center. All storage is for open systems workloads. There is 30 TB of unused capacity’.

Which of the following statements is true? A DS8800 customer would like to implement synchronous remote mirroring on an DS8800 using their existing dark fibre infrastructure between the two data centers.

They have strict regulations about data protection. Which of the following applies to DS8870 encryption? The maximum cache size of a DS8800 Model 951 is: A customer has an existing D68800 which is installed in their data center. It now must have an extra frame added to support additional capacity growth, but there is no room to fit the expansion frame to the right. Which option should be taken? In a DSSSOO controller which components are created during configuration of space-efficient (PTC-SE) storage in an extent pool? The customer’s data center has an elevator with a maximum load capacity’ of 2200 lb (1000 kg). A Disk Magic study has proved that the performance requirements of the workload are at Enterprise class levels. What should be recommended? Which function of the DS8000 allows a customer to move drives from CKD to fixed block without taking the system offline? What statement is correct regarding DS8870 Remote Pair FlashCopy? The DS8000 supports over 90 server platforms. Where is the most current and up-to-date list of supported platforms found? As with all types of technology. System z software occasionally needs to have maintenance applied to it to fix errors or to support enhanced functionally. In the System z environment, this maintenance is known as: A customer’s IT department has had problems meeting their backup window. They now mandate that a fast backup process be in place before an application is deployed. They have a DS8000 as their disk subsystem and a TS3500 tape library for backups. What is the simplest and most effective option to satis1i this requirement? A D38870 administrator would access the GUI using: A potential DS8OIJO customer would like to understand the size of the non-volatile storage (NVS) as compared to the overall size of the DS8000 processor memory. Which technical feedback to the customer is correct? A new DS8000 z/OS storage customer needs to configure the DSS000 system’s host adapter ports to Brocade SAN directors for host access in a Metro Mirror solution. Which protocols must be configured for this system? What is DS8000 Assist On Site (AOS)? The DS Command Line Interface (CLI) of the DS8800 can be used to perform which two of the following configuration actions? 1_ Assign RAID ranks to extent pools 2_ Install and activate the D68000 storage tier advisor tool 3_ Invoke a server failover/fallback 4_ Create and assign LUNs to hosts/servers The output of what tool is used as input to Disk Magic to most accurately model a Windows host that will be used with an IBM D38000? A customer has a UNIX-based 25 TB Oracle/SAP instance currently running on an HP 12000 Enterprise Storage array. The database is very sensitive to response times and is reported to have a peak I/O requirement of over 25,000 I/O per second. The HP device is nearly three years old, and the customer is considering replacing it. Which of the following is the best way to investigate the IBM DS8000 as a suitable technology replacement for the HP 12000 device? A Business Partner has just received a REP from a customer for new disk subsystems for their data centers which are 500 km apart. DS8000 Global Mirror will be proposed. The customer wants to manage the replication environment using off-the-shelf software rather than custom scripting. The customer already has EMC Symmetrix replicating between their data centers. Which of the following should be proposed to manage the D58000 replication? A pre-sales TDA must be done for the sale of a new DS8870. Which document type should be used for documenting the review details? Shortly after the installation of a DSS000 and before Call Home has been fully set-up, the customer notices an error message relating to a failed DS8000 primary power supply. What action should the customer take? Who is entitled to perform an IBM Secure Data Overwrite of a DSSS7O? Which statement is true of the Easy Tier feature on DS8000?

When I/O Priority Manager is enabled, each volume in a D38800 is assigned to a performance group at the time of the volume creation. What action will the DS8800 take to ensure that the most important volumes as defined to I/O Priority Manager receive the highest level of system resources available? A potential DS8870 customer knows that RAID 5 works much faster and is more capacity-efficient than RAID 6, but they fear for double disk failures due to high rebuild times at large disk sizes. How should the technical specialist address this concern? What should be used to most effectively model System z customer workload for implementation on IBM DS8800?
